have usually been riveted to the rubber'sole of the shoe by clinchingover the inner end of the spike. .With that type of constructionpressure on the spikes parallel to the sole of the shoe has caused thespike to be tipped about the edge of the flange on the spike, exerting apoweriul leverage upon the clinched end of the spike and causing thespike to be loosened and even withdrawn from the sole. Loosening of thespikes or withdrawing of them from the sole not only results in loss oftraction and discomfort to the wearer but also the openings left by thetear ing away of the spikes permit moisture to enter the shoe.

The principal objects of the present invention are to provide securityof attachmentwithout excessive stiffening of the sole of the shoe; toprovide comfort to the wearer and to eliminate ingress of moisture.

Other objects will appear from the-followlng specification and theaccompanying drawing.

Of the drawing:

Fig. 1 is a side elevation-of a spiked shoe embodying the invention inits preferred form, parts being shown in'section.

Fig. 2 is a bottom view of the sole oi the shoe.

Fig. 3 is a vertical section showing the manner of applying the spikeaccording to the invention.

' Referring to the drawing:

The shoe, which may be an overshoe designed to be worn over a leathershoe or a shoe to be worn directly upon the foot, comprises, forexample, an upper it, of rubber, which may be provided with a lining ifdesired, and a rubber sole ii attached thereto. A reinforcing layer-orlayers of 4 fabric or other reinforcing material i 2 maybe incorporatedin the sole, preferably in its inner face, and an insole i8 is alsocemented or vulcanized in place in the shoe.

Spikes M are each provided with a flange it 4 which engages the treadface of the sole and a shank l8 which extends through the sole Ii andfabric reinforcement l2 and has its inner end bifurcated to provideclinch members II.

In order to prevent tearing of the spikes from 50 the sole and also tosecurely seal the margins of (Cl. tid -7.6)

and the spike, and having an aperture of sufilcient size to freely admitthe shank when such shank is in its unclamped condition. In insertingthe spikes in the sole of the shoe use may be' made i of a rivet settingmember such as that shown at 5 is in Fig. 3, and a co-operating anvil2i), said anvil having a recess 2i in its face for receiving one of thewashers i8 and also having a conical projection 22 at the center of saidrecess surrounded by a groove 23 which cooperates to turn and -clinch 10the prongs of the spike. The rubber material of the sole, beingresilient, aids in maintaining the clamping pressure. y

In order that the clinched ends of the spikes will be depressed belowthe inner surface of the 15 sole and thereby provide comfort to thewearer without objectionable contact of the wearers foot with theclinched ends of the spikes, the inner sole i3 is formed with aperturesof such size as to clear the washers I8 and is made of such thick- 20n'ess as to exceed the projection of the clinched prongs of the spikeabove the sole. While an auxiliary insole may be provided, if desired,this is not essential for comfort, owing to the fact that the aperturesin the insole need not be so large 25 as to cause discomfort.

The metal washer securely attaches the spike to the sole of the shoewithout such stiffening of the sole as would occur were a reinforcingplate of substantially the area of the sole used as a fas- 30 toningmeans, so that the shoe provided with the spikes is substantially asflexible as a rubber shoe not so provided.

I claim:

An article of footwear comprising a thin flexible rubber sole, aperturestherethrough for receiving spikes, a plurality of metal spikes each having a bifurcated shank end adapted to be deformed within the shoe forclinching, and an in tegral flange for engaging the tread side of the 40sole, a layer or flemble non-metallic but substantially inextensiblematerial adhered to the inside face of the sole around the apertures toprevent spreading of the material at the apertures, a washer about eachshank at the inextensible layer, said washer, inextenslble layer andsole being held clamped against said use by the clinched end of theshank; and an insole at last substantially equal in thickness to the ersand the clinched ends of the shanks so as to present a substantiallyflush insole surface, said insole being adhered to. the sole within theshoe, and \searance openings to receive the washers.
